The selection cannot be run on any server [message #1016074]

I'm running Juno on an iMAC with all software at current releases.

I have installed the WTP tools and can edit source in JavaScript and HTML5. I can "run" HTML5 code by right clicking on the project and choosing Open with > Web browser.

However, when I click the Run icon I get the pop up "The selection cannot be run on any server." which is correct as Eclipse > Preferences > Server > Runtime Environments is empty. However Jetty and Apache are listed in the plugins. How do I configure Eclipse to "see" either Jetty or Apache so I can run on these as internal severs?

I haven't done precisely that since I always use Tomcat, but when you go
to add a new Server Runtime Environment and click Download additional
server adapters, is there not one you could use? I did see a Jetty
offering when I tried it.

OK, progress. I had tried to download various servers but they all failed with messages about missing components.

I managed to install these:
Jetty Target Components
JST Server Adaptors
WST Server Adaptors

Now I can see J2EE and HTTP Preview in the server list. However, when I run my code I get:

Server HTTP Preview at localhost failed to start.

I'll keep flailing around and see where I get but suggestions would be welcome. (I'm doing this by sheer guesswork, it would be nice if there were a step by step guide somewhere. I can't be the first person wanting to run HTML5 in Eclipse on Mac.)

You're not the first; it just may be the better part of a day before
some who's done it checks the forum.

Thanks. I'm not in any hurry (but I'm as patient as your average programmer).

Run On Server requires that the project have the necessary deployment information defined, and typically that's done by creating your content in a Static or Dynamic Web Project.

Thank you for the reply. Yes, I had set the project up as a static web project. I now have it running in a local J2EE preview server but cannot get the local HTTP preview server to run. Presumably I haven't installed some Jetty component.

My real issue is why is this so obscure. There ought to be step by step instructions. I have used Eclipse to develop simple apps in several languages and in every case (except C) I had to obtain expert guidance and install special plug-ins etc. Simple tasks ought to be accomplished simply. With Eclipse this does not appear to be the case.

Eclipse resources are a very good basis, but they tend to document not
synthesize and you're asking for synthesis.

You might find such help, you just have to stumble upon it. Google is
your friend. Sometimes, stackoverflow.com is remarkably helpful. In my
opinion, the best helps for Eclipse aren't to be found from eclipse.org,
but from developers who've gone to the trouble to write tutorials, some
of them very good like http://www.vogella.de. I do some of that (not as
good as Lars Vogel) on my own site and there are many others too.

I'm eager to help you, but I'm more on the Java/JEE side of things. I
write (mostly static) HTML and CSS web pages to help others out, but I'm
not a specialist and I just use Vim to do it--not Eclipse.

I hope you find some better help soon.

Best regards,

Russ

Problem "solved". It seems the trick is to install the entire Web, XML, Java EE and OSGi Enterprise Development software. I had only installed the components that looked as though they were needed. Nevertheless, the first install failed with errors on PHP tools, so I unchecked these and ran it again. I can now test HTML5 in Eclipse using the HTTP Preview Server.

Thanks to everyone who responded.

I would have had the same problem because I'm a bit of a minimalist myself.

So, down the road, if you ever feel like writing a tutorial, it will
apparently be very welcome to the next guy.
